That assumes a server and connection - but there are HTML5 UAs that will be working on local content (EPUB3, email, etc.) where all content is local and you need a mechanism that does NOT require a server on the other side.

hmm. It doesn't feel right to me. Not sure how exactly why.
Basically my *ideal* (utopian?) scenario would be
<img src="foo/the-image"/>
And then through content-negotiation the best image is chosen depending on
* screen size
* bandwidth
* etc.
